• O2 reaches 300 OTU (100% of allowed single or daily exposure).
• Nitrogen Bar Graph at the value (segment) selected.
• NORM/GAUG Ascent Rate Alarm - rate exceeds 60 FPM (18 MPM) when deeper than 60 FT (18 M), or 30 FPM (9 MPM) at 60 FT
(18 M) and shallower.
• Loss of the active Transmitter Link signal for more than 15 seconds during a dive.
• Entry into Decompression (NORM).
• Conditional Violation (above a required Deco Stop Depth for less than 5 minutes).
• Delayed Violation (above a required Deco Stop Depth for more than 5 minutes).
• Delayed Violation (a Deco Stop Depth greater than 60 FT/18 M is required).
• Delayed Violation (Maximum Operating Depth of 330 FT/100 M is exceeded).
• A Gas Switch to another tank would expose the diver to PO2 greater than 1.60 ATA.
• Watch Daily Alarm reaches time set (on surface only).
• Watch Countdown Timer reaches 0:00 (on surface only).
A single short beep (which cannot be disabled) is emitted for the following -
• Upon completion of a battery change.
• Change from Delayed to Full Violation 5 minutes after the dive.
3 short beeps (which cannot be disabled) are emitted for the following -
• NORM/GAUG Ascent Rate Warning - rate is 51 to 60 FPM (15.1 to 18 MPM) when deeper than 60 FT (18 M), or 26 to 30 FPM (7.5 to
9 MPM) at 60 FT (18 M) and shallower.
• FREE Dive Elapsed Dive Time Alarm - 3 beeps at each 30 second interval, if set On.
• FREE Dive Depth Alarms 1/2/3 (set sequentially deeper) - each 3 beeps 3 times.
• FREE Dive NIBG Alarm (Caution zone, 4 segments) - 3 beeps 3 times.
• Entry into Deco during a FREE Dive (Violation) - 3 beeps 3 times.
• Free Mode Countdown Timer reaches 0:00 - 3 beeps 3 times.
During the following NORM Dive situations, the 10 second continuous tone will be followed by a 5 second steady beep that cannot be
acknowledged/silenced -
• Ascending above a required Decompression Stop Depth for more than 5 minutes (referred to as a Delayed Violation).
• Decompression requires a Stop Depth of 70 FT (21 M) or deeper.
• Being on the Surface for 5 minutes after a Conditional Violation.
BACKLIGHT
To activate the Backlight, press the L (lower/right) button.
• The Backlight will activate and illuminate the display for button depression time* plus the Duration time set (0, 5, or 10 seconds) for a
maximum of 20 seconds.
*The Backlight turns Off if the button is held depressed for more than 10 seconds.
• Press L again to activate as desired.
NOTE: Extensive use of the Backlight reduces estimated Battery life. Also, the Backlight does not operate during a Low
Battery condition or when the AMPHOS AIR 2.0 is connected to a PC.
POWER SUPPLY
The AMPHOS AIR 2.0 uses (1) 3 volt CR2430 Lithium Battery. Used as a Dive Computer, the battery should operate normally for 1 year or
300 dive hours if 2 dives are conducted during each dive period. Voltage is checked every 2 minutes on the surface.
• If voltage decreases to the Warning level (2.75 volts), the Battery icon will appear on Surface Main (Fig. 3a) as an indication that the
Battery should be changed prior to commencing a series of dives.
• If the voltage decreases to the Alarm level (2.50 volts), the Battery icon will flash and the message CHANGE BATT will flash (Fig. 4)
for 5 seconds, then operation will revert to Watch Main Time. The AMPHOS AIR 2.0 would then only operate in Watch modes until the
Battery becomes completely depleted.
• Low Battery conditions are not displayed during dives.
• If a Low Battery Condition was not displayed prior to starting a Dive, and a Low Battery Condition occurs during the dive, there will be
sufficient Battery power remaining to maintain operation for the remainder of that dive.
Transmitters (TRTs) each use (1) 3 volt, CR2 Lithium Battery. A TRT's battery should provide normal operation for 1 year or 300 dive hours.
TRTs check battery voltage when they are pressurized and will send a Low Battery signal to the Receiver in the AMPHOS AIR 2.0 when the
voltage drops below the Warning level.
• TRT Low Battery conditions are only displayed on Status screens that can be accessed from the Surface Main.
To check the condition of the AMPHOS AIR 2.0 or a TRT's Battery if NORM or GAUG Mode is selected, depress the S button for 2 seconds
while viewing the Surface Main, then release it.
• As the button is depressed, the AMPHOS AIR 2.0's Receiver will activate.
• 2 seconds later, the AMPHOS AIR 2.0's Battery status will be displayed for 3 seconds (Fig. 5), then -
if active and linked, TRT 1's Battery status will be displayed for 3 seconds (Fig. 6A), then -
if active and linked, TRT 2's Battery status will be displayed for 3 seconds, then -
the display will then revert to Surface Main.
• If a TRT is not active and linked, the message NOT AVAiL (not available) will be displayed (Fig. 6B).
